(C1. @geniaal l, Claim This invention relates, to air Conditioners and has for its object to provide a comparatively Simple and inexpensive deviee of this ellaraeter that may be quickly installed f or domestic use or positioned in an automobile or other con- Voyance for either cooling or heating the air.

A further object of the invention is to provide an air conditioner in which a quantity oi liquid iS caused to continuously elreulate in n easing over a cooling Surface to chill the liquid, fresh nir being drawn in at one end of the easing and cooled by the. liquid before the ,nir is disentir-sed at the other end of said casing.

A further object is toy provide the air conditioner with a motor driven pump or impeller for circulating the cooling liquid and further to prof vide a fan for inducing a flow of air through a central conductor and in contact with spaced tubes connecting the liquid containers whereby the air is thoroughly cooled by the time it reaches the discharge end of said central conf ductor.

A still further object of the invention is generall'y to improve this class of devices so as to increase their utility, durability and efficiency.

In the accompanying drawings forming a part of this specification and which similar numerals of reference indicate corresponding parts in all the gures o f the drawings:

Figure l is a horizontal sectional View of an air conditioner embodying the present invention and showing the device supported in a horizontal plane,

Figure 2 is a transverse sectional view taken on the line 2 2 of lFigure 1.

Figure 3 is a longitudinal sectional view of the exit pipe showing the manner of controlling the discharge of either cooled or heated air therefrom, and

Figure 4 is a side elevation showing the device attached to the engine of an automobile and supported in a vertical plane.

The improved air conditioner forming the subject-matter of the present invention may be installed in either a vertical or horizontal position and used either for cooling or heating pur poses, and in Figure 1 of the drawings, the device is shown supported in a horizontal position and used for cooling or chilling air prior to the discharge thereof into the interior of the room of a dwelling or other building.

The air conditioner comprises a casing or housing li which may be either cylindrical or angular in cross section and is provided at its outer end with an opening 6 adapted to receive a central air conductor, indicated at 1.

Disposed within the casing 5 on opposite sides of the central air conductor 1 are spaced containers 8 and 9 preferably extending the entire length of said casing and adapted to contain suitable non-freezing liquid, indicated at lil. ranged at the rear of the casing 5 and communieating with the interior of the containers and Q through openings l l is an auxiliary container or header l2 having its opposite. ends provided with filling nipples I3 normally closed by detachable Closure eens lill Se that by removing? the dans I4 the eenling liquid may be poured into the auxin lary Container or header l2- Tlireeded in the ends of the oeps I4 are deteelieble eerew plugs i4 which are removed when the air conditioner iS used ln eouneetion with en automobile.

Disposed Withi the liquid Containers. kll and 9 and spaced from the adjacent walls thereof are Ine-taille. .containers l5 adapted, to reeeive e suitable refrigerant, .Suele es artificial or natural ice, for the purpose of Cooling the liquid ,llly which lieuidy in turn, eools the air, es will be more fully explained heren-.leiten Extending through suiteble peeking glands lli in. the easing and outer wall of the header l2 is a shaft l1, the inner end of yWillen ,is operatively unconnected with a suitable eleeti-ie motor lil whiell Serves to rotate saidy shaft. Disposed within the auxiliary container or header l2 and mounted on the shaft Il is a pump or impeller i9, the purpose of which is to circulate the fluid lll through the easing and in .Contact with the chilled walls of the containers l5 thereby to keep the liquid at a suineiently low temperature to insure proper Cooling of the air. The containers il and 9 are connected by a plurality of spaced tubes v2li which extend transversely of the central conductor 1 and form a source or come. munication between the interior of said containers so as to permit the liquid to flow from one container to the other when the pump is in operation. The containers l5 are provided with lling nipples 2l through which said containers i5 may be filled with any kind of refrigerant, said nipples being provided with closure caps 22 of any suitable construction.

Air is admitted to the central conductor 'I through a pipe 23, one end of which is open to the atmosphere while the other end thereof communicates with the interior of the conductor l, as best shown in Figure 1 of the drawings. A fan blade 24 is secured to the inner end of the shaft I1 for the purpose of drawing air inwardly through the pipe 23 and inducing a flow of air longitudinally within the conductor 1 to the discharge end thereof. A pipe 25 is secured to the outer end of the conductor 1 for delivering cooled air to any desired place within a room or other' enclosure. Interposed between the casing 5 and the containers 8 and 9 is a packing 26 of insulating material and this insulating material preferably extends entirely around the casing so as to thoroughly insulate the same. The outer ends of the refrigerant containers l5 are spaced from the outer ends of the liquid containers to form passages 21 so as to permit the cooling fluid to flow around the ends of said refrigerant containers.

In operation the header I2 and containers 8 and 9 are filled with a suitable non-freezing liquid through the nipples I3 of said header and the containers I5 lled with Dry Ice, natural ice, or other refrigerant through the nipples 2|. The motor I8 is then started which causes the pump I 9 to circulate the cooling liquid through the adjacent opening II and thence around the refrigerant container I5 in one of the liquid containers and thence through the tubes 20 to the interior of the other container 8 and back through the opening II to the pump, thus causing a continuous circulation of the cooling liquid within the casing. During the rotation of the motor the fan 24 will draw air through the pipe 23 and as the current of air passes through the conductor 'I it will come in contact with the tubes 20 and become thoroughly chilled before the air is discharged through the end of the conductor 'I into the interior of a room. As the cooling fluid surrounds the walls of the central conductor l and said fluid also circulates through the tubes 20, an extended cooling surface is presented to the now of air through the conductor thereby insuring thorough chilling of the air, as will be readily understood.

For use when the climate and temperature are such that warm air rather than cold air is desired, there is provided an electric heating element 39 which may be fixed to the walls of the conductor 'I in the opening 6. Wire conductors 4I] connect the heating element 39 to a source of electric supply for heating the element 39.

In Figure 4 of the drawings, there is illustrated a modied form of the invention in which the device is used for heating the tonneau of an autof mobile. In this form of the invention, the device is supported in a vertical plane and operatively connected with the water jacket 28 of the automobile engine by means of upper and lower pipes 29 and 3D, one of which is threaded in the upper nipple 3| of the header and the other in the lower nipple 32 after removing the closure plugs I4 shown in Figure 1. It will thus be seen that hot water from the jacket 28 of the engine will enter the header through the pipe 29 and thence iow within one of the liquid containers 33 and through the spaced connecting tubes 34 to the other container and back to the water jacket through the pipe 30 thereby to heat the walls of the central air conductor 35 so that air ilowing through said conductor and coming in contact with said heated walls and with the tubes 34 will be thoroughly heated and delivered into the tonneau of the automobile in a warm condition.

When using the device on an automobile, I preferably provide the extension pipe 25 with one or more discharge nipples 36, the upper end of each of which is closed by a perforated plate 3l, the discharge of the air through the perforations in the plates being controlled by sliding cut off plates or dampers, indicated at 38.

It will, of course, be understood that the air conditioners may be made in diierent sizes and shapes and formed of any suitable material without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

An air conditioner comprising an outer casing open at one end and having an insulating lining, a pair of refrigerant liquid containers in said casing extending along the length thereof and spaced apart transversely of said casing forming an air conductor therebetween opening through the open end of said casing, refrigerant containers in each of said liquid containers spaced from the Walls thereof providing liquid conducting passages about the refrigerant containers, a header at the closed end of said casing connecting said liquid containers and extending through opposite side walls of said casing, tubes between said spaced liquid containers extending across said air conductor, an air inlet pipe through a side wall ci said conditioner at the closed end communicating with said air conductor, a ian in said air conductor for iowing the air between said liquid containers and over said tubes and means for circulating the liquid through said liquid containers, said tubes and said header.
